1.  Division established.  There is established within the department the Division of Administrative Hearings, referred to in this section as "the division," to hear and decide appeals from decisions pertaining to chapters 7 and 13 and any other appeals as the commissioner may require.  

2.  Oaths and witnesses.  In the discharge of the duties imposed by this chapter, the commissioner, the division and any duly authorized representative of the commissioner or division has the power to administer oaths and affirmations, take depositions, certify official acts and issue subpoenas to compel the attendance of witnesses and the production of books, papers, correspondence, memoranda and other records determined necessary as evidence in connection with a disputed claim or the administration of this chapter. Oaths and affirmations required by reason of duties performed pursuant to this chapter may be administered by any persons as may be designated for the purpose by the commissioner. In the discharge of the duties imposed by this chapter, the commissioner, the division or any duly authorized representative of the commissioner or division, when the interests of any interested party demand, may issue commissions to take depositions to any unemployment compensation or employment security official empowered to take such depositions under this chapter or the laws of any other state, for any of the following causes:  

3.  Refusal to appear.  A person who without just cause fails or refuses to attend and testify or to answer any lawful inquiry or to produce books, papers, correspondence, memoranda and other records, if it is in that person's power to do so, in obedience to a subpoena of the commissioner, the division or the duly authorized representative of the commissioner or division commits a Class E crime. This crime is a strict liability crime as defined in Title 17‑A, section 34, subsection 4‑A. If a person refuses to obey a subpoena duly issued by the commissioner, the division or the duly authorized representative of the commissioner or division, any court of this State within the jurisdiction of which the person resides or transacts business has jurisdiction to issue to that person an order requiring the person to appear and produce evidence or testimony, and any failure to obey that order may be punished by the court as contempt of court.  

4.  Protection against self-incrimination.  A person may not be excused from attending and testifying or from producing books, papers, correspondence, memoranda and other records before the division or any duly authorized representative or in obedience to the subpoena of the division or the duly authorized representative in any cause or proceeding before the division or any duly authorized representative on the ground that the testimony or evidence, documentary or otherwise, required of that person may tend to incriminate that person or subject that person to a penalty or fine; but an individual may not be prosecuted or subjected to any penalty or fine for or on account of any transaction, matter or thing concerning which that person is compelled, after having claimed privilege against self-incrimination, to testify or produce evidence, documentary or otherwise, except that the individual in testifying under this subsection is not exempt from prosecution and punishment for perjury committed in testifying.
